This was because keystoneclient had its own EC2 v4 signatureimplementation.

Consequently, EC2 v4 signature calculations would fail.With this update, CanonicalQueryString is set to an empty string when usingPOST and calculating AWS Signature Version 4 (this follows the implementationused by the AWS and boto clients).As a result, EC2 Signature Validation now succeeds.
